The present invention relates generally to a computer-implemented method for analyzing data of retail stores, and more particularly to a computer-implemented method for identifying similar stores.
Slow moving goods such as fashion apparel often have very sparse sales. It becomes a problem when one needs to model or forecast demand at an item/store level. A common approach is to borrow information from other stores. However, the other stores have generally different behaviors. While the information of the other stores is used, it must be sure that the other stores are, in some ways, similar to the store. Therefore, similar stores should be identified. The similar stores are typically identified through using store attributes such as geographic locations, climate zones, and population types. This approach to identify the similar stores using the store attributes is not robust enough because of the following reasons. The store attributes can only provide information of averaging all items or categories in each of the similar stores but do not provide enough information at item or category levels. Typically, the similar stores have a very limited number of the store attributes and frequently do not well maintain information of the store attributes. The store attributes are indirect indicators of store similarity.
Embodiments of the present invention provide a computer-implemented method and a computer program product for identifying similar stores and determining store parameters based on the similar stores. One or more computer programs identify key items for a plurality of stores. The one or more computer programs assign feature vectors to respective ones of the plurality of stores, each of the feature vectors comprising values of a behavior for the key items. The one or more computer programs determine a similarity distance between each pair of the vectors. The one or more computer programs identify similar stores of a respective one of the plurality of stores, based on the similarity distance. The one or more computer programs determine one or more parameters for a respective one of the plurality of stores, based on the similar stores.

There are potentially many ways to select the key items. Currently, an implemented approach is to choose a fixed number of items with the highest revenue in the last year. The rationale of this approach is that these items are most influential within a category, and high sales provide some confidence that most stores have sales. Selecting the key items based on only revenue has one potential problem; it may select similar items as the key items, for example, the same product but different sizes or colors. The approach is undesirable, because the similar items have strongly correlated behaviors in a majority of stores. These similar items as the key items should be avoided; therefore, it is desirable to have only one such item as a key item.
As an example, ten items with highest revenue selected from some swimwear categories are listed in Table 1. In Table 1, there exist some similar items. In Table 1, two items of ranks 1 and 2 are actually the same product with different sizes (M and S). In Table 1, items of swim shark panama (rank 4) and swim bubble panama (rank 6) are two similar items which are just different in style.

As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method, or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, and micro-code), or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module”, or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.
Any combination of one or more computer readable medium(s) may be utilized. The computer readable medium may be a computer readable signal medium or a computer readable storage medium. A computer readable storage medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples (a non-exhaustive list) of the computer readable storage medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device.
A computer readable signal medium may include a propagated data signal with computer readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device.
Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF (radio frequency), and any suitable combination of the foregoing.
Computer program code for carrying out operations for aspects of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java®, Smalltalk, C++ or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
Aspects of the present invention are described below with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer readable medium that can direct a computer, other programmable data processing apparatus, or other devices to function in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the function/act specified in the flowchart and/or block diagram block or blocks.
The computer program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other devices to cause a series of operational steps to be performed on the computer, other programmable apparatus or other devices to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide processes for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.
